What is Deltarune Fight Simulator?
Deltarune Fight Simulator is this site’s browser play page for Battle Simulator V4, a Scratch fan project by Scube3000. The game runs through TurboWarp and takes inspiration from DELTARUNE’s battles. You can launch it here without installing a separate game client.
Deltarune Fight Simulator is an independent fan resource, not the full DELTARUNE game or an official chapter release. DELTARUNE belongs to Toby Fox and the original team; the V4 project retains its creator’s credits. Other encounters, including Jevil, Spamton NEO and the UNDERTALE-inspired battles, have separate pages in the game selection above.

Deltarune Fight Simulator FAQ
❤️ Q01Which Deltarune Fight Simulator version can I play here?
This Deltarune Fight Simulator page loads Scube3000’s Battle Simulator V4, Scratch project 613803664, through TurboWarp. It is a standalone fan project inspired by the original battles, not an official DELTARUNE release.
❤️ Q02How do I start Deltarune Fight Simulator?
Press the green flag to launch Deltarune Fight Simulator. Choose Create new profile or Load existing profile. For a fresh start, select your control scheme, enter a player name and confirm with the on-screen buttons.
❤️ Q03Why are Deltarune Fight Simulator controls not responding?
Click inside Deltarune Fight Simulator so the player receives keyboard input. Desktop controls use arrows or WASD to move, Z to confirm and X to cancel. If you selected Mobile controls, use the on-screen buttons or switch modes in Options.
❤️ Q04Can I play Deltarune Fight Simulator on my phone?
Deltarune Fight Simulator includes Mobile controls with a D-pad and Z/X buttons. Select that mode during setup and try landscape orientation. Touch performance varies; use a desktop keyboard if your device cannot run the player comfortably.
❤️ Q05How do I save in Deltarune Fight Simulator?
Before leaving Deltarune Fight Simulator, obtain your save through the in-game Options app. Keep it for Load existing profile next time. Do not assume a refresh preserves progress: this site does not provide cloud saves or backups.
❤️ Q06Why is Deltarune Fight Simulator blank or not loading?
Give Deltarune Fight Simulator time to load its assets and press the green flag. If loading stalls or question-mark sprites appear, save any accessible progress before reloading. Try again later if the embedded project remains unavailable.
